METHOD AND DEVICE FOR CORRECTING ARTEFACTS DURING X-RAY IMAGERY, ESPECIALLY COMPUTER TOMOGRAPHY, OR RADIOGRAPHY, BY MEANS OF TEMPORAL MODULATION OF THE PRIMARY RADIATION

摘要

Artifacts caused by scattered radiation when generating X-ray images of objects are corrected using a temporally alterable modulation of the primary radiation. A respective set of originally amplitude-modulated modulation projections of the object is generated and a respective scattered image allocated to the respective modulation projections is calculated. The method is particularly suitable for fast CT scans.
